IMPRGVEMENT IN SDA-FOUNTAINS.

Specification forming part of Letters Patent N o. 128,410, dated June25, l872; antcdated .I une 19, 1872.

1 o all whom it may concern.'

Be it known that I, JOHN MATTHEWS, of the city,`county, and State of NewYork, have invented certain new and useful Improvements in Apparatus forDispensing Soda-Tater and other aerated or gaseousA liquids and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanying drawingforming part of this specification, and in which- Figurel representsavertical transverse section of an apparatus constructed in accordancewith my invention, and Fig. 2 an irregular vertical longitudinal section0f the same. Fi g. 3 is a front view, upon an enlarged scale, of thedraught-arm with its attachments; Fig. 4, a side View thereof; and Fig.5, an inverted plan of themouth-pieee of the draught-arm. Fig. 6is aplan of the cooler arranged within said apparatus.

Similar letters of reference indicate correspondin g parts throughoutthe several figures of the drawing.

My invention consists in an apparatus for dispensing soda-water andother aci-ated or gaseous liquids, in which the draught-arm of theapparatus is provided with a mouth-piece constructed to adapt it ytodrinking cups or tumblers, whereby the latter are filled under pressure.The invention also includes a combination, in one and the sameapparatus, of a device t'or drawing under pressure, with a cooler forthe gaseous liquid, whereby the gas is more perfectly or fully retainedin the water, otl which said liquid is composed. The inventionfurthermore comprises a helical currentcooler, which has the effect ofmore perfectly cooling the liquid. It also includes a spirally arrangedor constructed nozzle or outlet from the draught-arm, by which thegaseous liquid is introduced in a spiral stream around the interior ofthe cup or tumbler, thereby preventing violent commotion and preventingescape ofthe gas from the incoming liquid. Furthermore, the inventionembraces a combination of a tumbler-guardfwith a draught or dispensingarm; likewise numerous details, including a tumbler-holder, incombination with said arm. The invention also consists in a combinationof gas iixtures and tubes for conveyin g illuminatin g-gas with anapparatus for dispensing aerated liquids, when said tubes (if more thanone) are arranged to run up through or within said apparatus-that is,through the ice-chamber or up within its walls-and so that they formpart of the apparatus, ready for the attachment of gas-pipes to eiiectthe necessary illumination for using the apparatus by gaslight and tolight up the same.

In the accompanying drawing, A represents the outer case of an apparatusfor dispensing soda-water or other aerated liquid. This case may be ofmarble, and of any desired design or pattern. B is the interior case orice-chamber of the apparatus, having its sides and bottom made hollow ordouble, as usual, for reception of a suitable non-conducting material orpacking. C is the dispensing or draught arm of the apparatus, arranged,as ordinarily, to project through the one side ot' the structure fromwithin the interior case B, where it is connected, by a pipe, b, withthe cooler, to the outside of and beyond the outer case A, said armbeing provided externally with a suitable cock or tap, D, for opening orclosing and controlling the draught, and being furthermore provided witha mouth piece, E,

through which the liquid is passed from the draught-arm. Thismouth-.piece is of an inverted cup-form or other equivalentconstruction, with a soft and flexible pad, c, which may be of rubber,arranged within it-that is, upon its under side or facesurrounding theaperture in it through which the liquid is passed from the draught-arm,and of proper dimensions to constitute a packing to the outer edge ofthe tumbler or cup when the latter is held or pressed up against it,whereby I am enabled to iill said tumbler or cup under pressure, thusavoiding the waste of the gas consequent up on drawing the aeratedliquid into a receiver or tumbler exposed at its mouth to theatmosphere. In connection with tliis feature or dcvicefor dispensing theliquid under pressure the cooler, irrespective of its peculiarconstruction, but arranged within or combined with the same apparatus,performs an important function or adds to the strength of the chargewith which the liquid passes into the tumbler, inasmuch as the liquidbeing kept cool the water of which it is composed is made to retain alarger proportion of the carbonicacid gas. Said cooler is represented asconstructed of two (or there may be more) cylindrical vessels, F F',arranged side by side within the ice-chamber B. Such coolerthat is, eachone, or it may be both or all of them, if two or more be used-isconstructed to produce a helical current of the .liquid passing throughit, whereby said liquid is spread or caused to travel in a thin streamover or in contact with the interior of the shell of the vcooler,thereby more eft'ectually cooling the liquid as it passes ythrough thecooler. Thus, the aerated liquid is introduced, as by a pipe, d, fromthe generator into the first cooler F, at or near its one end, onto orwithin a spiral conductor, e, which imparts to the liquid a helicalcourse through or along said cooler and distributes it in a thin streamagainst the interior of the outer wall or shell thereof', and on theliquid reaching the opposite end of such cooler it is caught or receivedby a hollowT spiral shield, f, which leads it into or against a secondspiral conductor, e', in the next cooler F', so as to make it assume afurther or repeated helical course through the latter cooler in areverse direction, and when arriving at the far end of saidlast-mentioned cooler the liquid is again caught by a second hollowshield, j", and conducted into the pipe b, which connects with thedraught-arm. Upon the aerated liquid leaving the draught-arm to enterthe tumbler Gr it is desirable to conduct it into the tumbler in aspiral stream around the interior of the latter, for which purpose theliquid is delivered through a lateral and spirally arranged orconstructed nozzle, g. This prevents or reduces that violent commotionof the liquid on entering the tumbler which is apt to disengage thecarbonio acid from the water composing said liquid. Such nozzle g may beconstructed to form a part of the mouth-piece E, as shown in thedrawing. h is a safety-valve attached to the mouth-piece E to preventany excessive pressure ofthe gas likely to endanger the bursting of thetumbler. H is a tumbler-guard connected with the drau gh t-arm C or itsmouth-piece E to prevent accident or damage in case ofthe breakage ofthe tumbler when being iilled under pressure. The tumbler-holder I, usedin combination with the draught-arm, is constructed with a cushionedfoot-piece, i, onto which the tuinbler is placed, and said holderelevated by a screw, k, to bring the mouth of the tumbler G up againstthe pad c of the mouth-piece E, which latter, with its attachedtumbler-guard, may be titted to swivel or turn on a vertical axis incommon ,with the tumbler-holder, that is connected with the mouth-pieceby side studs l oi' the latter, arranged to t slots m in the sides ofthe holder. M M are tubes, of which there may be one or more, providedwith burners at top for conveying and using illuminating-gas to light upthe apparatus, the same forming gas-fixings, which are combined with theapparatus as a part and parcel of it, so that said apparatus forms acomplete illumina-ted one when adjusted to its place, and only requiresan ordinary connection with the gas-pipes from below. 'lhese tubes M Mare arranged to run up through or within the apparatus-as, for instance,up through or Within the non-conducting material between the Walls ofthe ice-chamber B, or through the interior of said chamber-when theyshould be clothed or protected by rubber or other suitable material.

lVhat is here claimed, and desired to be secured by Letters Patent, is-

l. The draught-arm of an apparatus for dispensing soda-Water and othergaseous or aerated liquids, fitted or provided with a mouthpiececonstructed to hermetically seal a drinking cup or tumbler,substantially as and for the purpose herein set forth.

2. The combination of the cock I), the draughtarm O, and thetumblersealing mouth-piece E, and clamp I, essentially as described.

3. The combination, with the draught-arm (3, ofthe spirally arranged orconstructed nozzle g, essentially as herein set forth.

4. The combination of the spirally arranged or constructed nozzle g withthe tumbler-sealing mouth-piece E,.clamp I, and the draughtarm C,substantially as described.

5. The combination of the tumbler-guard H with the tumbler-sealingmouth-piece E, clamp I, and the draught-arm C, essentially as speciiied.

6. The cooler or coolers F F', constructed substantially as described,whereby the liquid is passed in a helical current or currents throughsaid cooler or coolers, and in contact with the interior of the shellthereof, as specitied.
